Today we’re going to create a library to use a simple RESTfull API for a great project called Gzaas. Don’t you know what the hell is Gzaas? Gzaas is simple idea idea of a friend of mine (hi @ojoven!). A simple project that creates cool mesages on full screen. Then you can share the link in twitter, facebook and things like that. Yes. I now when I explain it, the first word that appear in our minds is WTF, but it’s cool, really cool.

Ok. The API is a simple RESTfull API, so we can use it with a simple curl interface. A few lines of PHP and it will run smoothly. But Gzaas is cool so we’re going to create a cool interface too. This days I’m involved into TDD world, so we’re going to create the API wrapper using TDD. Let’s start.

The first version of Gzaas API is a very simple one. It allow to create new messages, and we also can list the whole set of styles, patterns and fonts availables. The idea is build something as modular as we can. Problably (I hope so) Gzaas will include new features in a future, so we don’t want to build a monolitc library. We are going to start with fonts. As we can see in documentation we need to perform a GET request to get the full list of available fonts. There’s an important parameter (nowFeatured) to show only the featured fonts (the cool ones).

use Gzaas\Api;
$fonts = Api\Fonts::factory()->getAll(Api::FEATURED);

So we are going to crate a simple test to test our font API.

$this->assertTrue(count($fonts) > 0);

With this test we’re going to test fonts, but we also can test styles and patterns.

because of that there’s a simple bootstrap.php file to include all files. But we’re going to take a step forward. We’re going to create phar archive with the whole library inside. The creation of phar archive is very simple. We need a index.php file with the bootstrap (it must end with a __HALT_COMPILER();)
